The crowd at Seattle Seahawks home games are collectively called 'The 12th Man'. So it was only natural that a Seattle couple has named their new baby '12th Mann'. Seriously.

But the team's biggest fan will probably sleep through the entire Super Bowl, that's because she'll only be a few days old.

A Seattle couple, whose last name happens to be Mann, welcomed the arrival of a baby girl this week who they've named Cydnee Leigh 12th Mann. That is the child's legal name. And they didn't even spell out the word twelfth. They actually used numbers. But obviously, as die-hard Seahawks fans, it was something that just made a ton of sense.
